This icon is a file folder symbol with the wi-fi network symbol in the upper right corner. The wi-fi symbol has been transposed to fit within the corner and it is shown upside down with the smallest dot at the top rather than the bottom. The wi-fi symbol is also at a 45 degree angle rather than straight up and down which is how the icon is normally visualized.

This is the FTP icon for Windows 10. Here we go. Optimized for 32x32 px, these are the simplest icons in the line style. Downloadable formats are PNG and SVG, among others. Icons8 icon pack is unique in providing a huge number of icons designed by the same team of four designers who create the new icons every working day in the same style and with the same quality. Same cool as the Bat Face, huh.
